...should a healthy 40-year-old woman be able to dig per day? I've found that three is my limit, and I'm sore and discouraged. I wanted to do this myself, and not get DH to hook up the auger on the tractor. I only have to dig nine, for heaven's sake, but these posthole diggers are about to get the best of me. I'm planting my posts two feet deep. Have three more to go, and hopefully I'll get them done tomorrow, if I can move. I'm just so insulted--I thought I was in better shape than this! Those darn chickens better appreciate their new run.
